Conjugate coordinates

If the rectangular conjugate of the polar vector 12 angle 35 degrees is equal to x+yi, find the sum of x and y.

Final Answer:

s =  2.9469

Step-by-step explanation:

α=35   x=12 cosα=12 cos35° =12 0.819152=9.82982 y=12 sinα=12 sin35° =12 0.573576=6.88292  s=x+y=9.8298+(6.8829)=2.9469
